Imagine... painted lady #butterflies (Vanessa cardui) emerging in NW Europe in august, migrating to W Africa, then being blown across the Atlantic to French Guyana in S America. Insect #migration is AWESOME! 😍 #insectmigration #nature https://www.nature.com/articles/s41467-024-49079-2
A trans-oceanic flight of over 4,200 km by painted lady butterflies - Nature Communications

The extent and impact of global insect movements is hindered by tracking limitations. This study reveals a 4,200 km transatlantic journey by butterflies from West Africa to South America, lasting 5-8 days, highlighting the remarkable capacity of certain insects to disperse over vast distances.

The 30-meter pass in the Pyrenees through which millions of insects migrate

Scientists from the University of Exeter have documented the massive movement of arthropods through Bujaruelo, where researchers detected up to more than 3,000 flies per meter and minute

@lenahallesaale That's a great question! #InsectMigration probably differs from bird migration in many aspects, because they would often repeat generations while migrating. Some butterflies are known to do similar things, as far as I know. People studying the migration of #MonarchButterflies might know more about how these animals find their way while repeating generations.
